Allinol is the racing fuel promoted in Pixar's Cars 2.
In the film, Sir Miles Axlerod presents Allinol as an environmentally friendly alternative fuel and uses the World Grand Prix to promote it internationally. The fuel becomes central to the spy plot when racers using it are remotely manipulated into dangerous engine failures.
The storyline links the fictional fuel to Axlerod's larger plan to discredit alternative energy and profit from a different fuel source. Mater, Lightning McQueen, Finn McMissile, and Holley Shiftwell gradually uncover the conspiracy during the international race tour.
Allinol is easy to confuse with Rust-eze, the bumper ointment brand that sponsors Lightning McQueen, or with the fictional racing teams and fuel brands shown around the Piston Cup. Allinol belongs specifically to Cars 2's World Grand Prix storyline and is not the central fuel brand in the first film.
